MAKE THE ROOM MOVE WITH THE MUSIC RhythMic turns nearby sound into a full-screen light show. Pick a color, animated pattern, or occasion theme, then watch every beat reshape the screen in real time. NEW: HALLOWEEN NIGHT Glowing jack-o'-lanterns, bats, ghosts, and a full moon react to every beat — perfect for Halloween parties. Premium is a one-time lifetime purchase with Family Sharing. ADAPTIVE SOUND ENGINE RhythMic listens through your microphone and continuously adapts to the room. Recalibrate at any time, adjust sensitivity manually, or let Adaptive Mic Sensitivity keep the response balanced as the music changes. BASS, VOCALS, AND TREBLE Real-time frequency analysis separates low, mid, and high energy. Bass can drive powerful pulses, vocals can animate the center of the scene, and treble can add detail and sparkle. You can also tune Bass Response in Settings. 50 MUSIC-REACTIVE VISUALS Explore solid and dual colors, flowing gradients, glowing ripples, particles, waveforms, equalizer shapes, tri-band visuals, and celebration scenes for birthdays, weddings, graduation, New Year, Ramadan, Eid, and more. LIVE PERFORMANCE Build a scene timeline, choose manual or timed transitions, set each scene's intensity, reorder the running show, and control the result from one dedicated performance workspace. SYNC THE ROOM Host a secure multi-phone party over local Wi-Fi so nearby iPhones follow the same colors. Extend the show to Apple Watch, the flashlight strobe, Live Activities, and a connected external display when supported. CREATOR RECORDER Record the screen alone or combine it with the front camera, back camera, or both cameras at once on supported devices. Choose microphone audio, trim the result, frame it for 9:16, 1:1, or 16:9, and export a ready-to-share video. DESIGNED FOR THE MOMENT • Automatic mode keeps visuals moving without music • Double-tap the on-screen label to leave a show • Triple-tap to reveal the sensitivity control • Optional haptic beat feedback • Inverted visuals and safety controls • English, Arabic, Spanish, Hindi, Simplified Chinese, French, German, Italian, and Portuguese PREMIUM, ONCE Unlock every premium visual and creator feature with one lifetime purchase.

SyncLight turns every phone in the room into one synchronized light show. Create a room, friends join with a code or a QR code, and every screen flashes, pulses and changes colour together, on the beat. Perfect for parties, birthdays, weddings, concerts, festivals, clubs, school and church events, and cheering in the stands. WHY PEOPLE LOVE SYNCLIGHT • One tap for the whole room: the host starts an effect and every phone joins in, in time • Join in seconds with a room code or QR code. No sign-up • 10 free effects: flash, strobe, rainbow, police, RGB pulse, breathing, colour fade, beat 120 and 128, fireworks • 80 VIP effects: neon tunnels, laser stars, derby lights, meteor rain, hearts, fireworks, countdowns and more, with new effects added regularly • Live pad for the host: Burst, Blackout, Flash and Next scene, on every phone at the same moment • Torch mode: the camera light flashes with the effect • Effect Workshop: create your own effects with colours, patterns, particles and your own words (names, wishes, team chants), then play them for the room • Playlists: chain effects into a whole show, with messages, event colours and a countdown • Tempo control and tap tempo to follow the music • Theme filters: lively, festive, romantic, chill, with words FOR BIG EVENTS • Event tickets: 24 hours of a big room for 50, 100, 200, 500, 1,000 or 5,000 phones, with every Pro feature. No subscription • The same room code and QR code for the whole event SYNCLIGHT PRO • Every VIP effect with no time limit, torch mode, your own effects and playlists for the whole room, rooms of up to 50 phones and a Pro host badge • Coming to Pro: DJ mode, music sync and event mode • Without Pro you can try VIP effects for 3 minutes at a time HOW IT WORKS SyncLight sends only tiny timing messages, never video. Each phone draws the light itself, so the whole room stays in sync, on Wi-Fi or mobile data. SAFETY Some effects use bright, flashing light. A safety warning appears before they play, and flashing is kept to a safe rate. Stop if anyone feels unwell. SUBSCRIPTION Payment is charged to your Apple ID at confirmation of purchase. The subscription renews automatically unless cancelled at least 24 hours before the end of the current period, and your account is charged for renewal within 24 hours before the end of the period. Manage or cancel it in your App Store account settings. Terms of Use: https://synclight-codex.web.app/terms-of-use.html Privacy Policy: https://synclight-codex.web.app/privacy-policy.html
